Abstract
Techniques are disclosed relating to video signal-to-noise ratio (VSNR) measurement. In one embodiment, an analog television signal receiver includes a measurement circuit configured to measure noise in a video signal over one or more intervals that correspond to a horizontal control signal of the video signal and a control unit configured to determine a VSNR based on the measurement. In another embodiment, a first noise calculation circuit is configured to determine first noise information from a video signal and a second noise calculation circuit is configured to determine second noise information from a video signal in a manner different from the first noise calculation circuit. A control unit may be configured to generate a VSNR based on one or both of the first noise information and the second noise information.
